Work is a scalar quantity and is equal to the product of the magnitude of the displacement and the
component of the force in the direction of the displacement.

Physical quantities and units
Physical quantities are characterized by their numerical value (magnitude) and associated units. The
numerical value and the unit of a physical quantity must be separated by space (for example: 21 Kg not 21kg).

Some properties of nuclei
Most of the atomic mass is concentrated in the atomic nucleus consisting of Z - protons and (A - Z)
neutrons.

Fundamentals of waves
In general, a disturbance that propagates from one place to another is referred to as a wave. Waves
propagate with well-defined speeds determined by the properties of the material through which they travel.
The mechanical waves requ

Problem 1: A sledder, starting from rest, slides down a 10 m high hill. At the bottom of the hill is a
long horizontal patch of rough snow. The hill is nearly frictionless, but the coefficient of friction between the
sled and
